WebFlagella: Bacteria can have one or more flagella (singular: flagellum). These can rotate or move in a whip-like motion to move the bacterium. ... Eukaryotic cell (plant and animal cell ... WebIn eukaryotic cells, flagella are microtubule bundles composed of dynein and a plasma membrane that is powered by ATP to make a blending motion. Prokaryotic locomotive structures are instead composed of repeated flagellin, a hook, and a motor complex attached to the cellular membrane that is powered by protons to make a rotator motion.
